A version of "Guantanamera" sung by Pete Seeger figured significantly in the plot and mood of Don McKellar's "Last Night", a 1998 movie starring McKellar, Sandra Oh, Callum Keith Rennie, David Cronenberg, Sarah Polley and Genevieve Bujold. The movie follows individual people preparing for the last six hours of their lives as the Earth faces oblivion from an unstated but absolutely inevitable and unavoidable oblivion. Once you hear the song as it is used in the movie, it will be difficult to associate the song with anything else.
